Helc is not enough...there are fdl for pwm and others to make it work error-free

[zygi898]

I have G31 europe and install LCI tail light, I level 07-21 add HELC code BDC, KOMBI and make FDL coding:
BL_L_CCM: ccm_346 [01 5A]
BL_L_IS_LED: nicht_aktiv, default [00]
BL_L_MIN_PWM: 5% [05]
BL_L_WARMUEBERWACHUNG: nicht_aktiv [00]
BL_R_CCM: ccm_345 [01 59]
BL_R_IS_LED: nicht_aktiv, default [00]
BL_R_MIN_PWM: 5% [05]
BL_R_WARMUEBERWACHUNG: nicht_aktiv [00]

Lights works but i have fault left and right OUTER stoplight.
Any suggestions?

Hi,
I got rid of the problems by fdl-coding in addition to the HO-WORD: HELC by changing following values:

ECU: BDC
BL_L_Warmueberwachung: "nicht_aktiv"
BL_R_Warmueberwachung: "nicht_aktiv"
BL_L_CCM: "off"
BL_R_CCM: "off"

Then I deleted the fault memory and went through a service function as on of the rear brake lights told "short circuit".
After the whole procedure I locked the car and let it sleep for 20 mins. All errors were gone and lights worked like a charm. (testing in for a month right now)
Hope this helps.

cheers

No, I did all these steps.
After bus sleep the new fault memory is triggered but lights are workin till circuit counter 255

And thats why the driver wont get any error
BL_L_CCM: "off"
BL_R_CCM: "off"

BL_L_CCM: "off"
BL_R_CCM: "off"

In both cases was fault for outer STOP lights?

In my case it was. I even had blinking and malfunction of outer brake lights.

Hi


I had exactly the same problem, try everything also update several times always newest ilevel but newer succes after some time the problem come back. There is an original retrofit cable about i have never found any info, but it is for the G30 Lci tail lights retrofit and it helped me with the same issue as you have. Original part number  61115A3C023  

And save the HO-WORT  HELC to the VO i was able to save it.

I hope it will help you.

Hi
I need a wire diagram for the LCI inner lamp.
The car is pre LCI US and EU LCI lamps were installed.
I changed the pins in the inner lamp but I still don't have the stop light in the inner lamp.
in TIS I only have a diagram for preLCI

[Airbus]

its me again. i am unable to fix the issue!

evrything works perfect but on every engine start the outer brake lights go off for 2 seconds and set the dtc see attached.
after 3-4 weeks the brakelight channels are blocked by bdc.

attached:
fault memory
cafds of bdc
fa of the car

maybe any1 has a solution for it

[krug]

it is faulty tail lights, enough to update bdc and code with HELC.
